[Energy expenditure in soldiers working on the public road and railroad construction]

The studies consisted in the determination of energetic expenditure of soldiers building roads and railway lines in different regions of the country and in different local conditions. In eight-hours' working days the calorific cost of 53 activities was determined. The studies involved 155 soldiers. The soldiers were occupied at earth work, surface work, production of asphalt and concrete, tract and sewage construction, operation of mechanized equipment. The energetic cost of the activities performed by the soldiers ranged between 3.1--13.0 kcal/min. and when converted per body weight kilogram 0.0435--0.1866 kcal/min/kg. As we miss the data on the energetic expenditure of workers building roads and railway lines the obtained results may be used at the ergonomic analysis of workplaces and at setting-up of an appropriate caloric value of food.
